Description

Technical Field

[0001] This utility model relates to the field of plastic screening machine technology, and in particular to a high-precision plastic color screening machine. Background Technology

[0002] Plastics are polymeric materials formed by adding plasticizers, stabilizers, colorants and other additives to synthetic resins through addition or condensation polymerization. The characteristics of plastics include plasticity, corrosion resistance and lightweight. They are widely used in packaging, electronics, construction and other fields. According to their use, they can be divided into general plastics and engineering plastics. They are the cornerstone materials of modern industry and have both performance and cost advantages.

[0003] The working principle of the high-precision plastic color sorting machine is based on multispectral imaging and intelligent decision-making: when the material passes through the detection area, the multispectral light source illuminates the surface, the sensor collects color, reflectivity and transmittance data, the image processing chip converts the data into digital signals, and the AI ​​algorithm compares the data with the preset threshold to determine the off-color particles. The control system triggers the high-pressure air valve or ejector plate to accurately remove the off-color particles.

[0004] Traditional plastic color sorting can be done manually, but this sorting method is time-consuming, labor-intensive, and has low recognition efficiency. With the rapid development of machine vision technology and artificial intelligence, workers have begun to try to use machine vision technology to identify plastic colors. However, current plastic color sorting machines can usually only select plastics of a certain color and cannot screen and collect plastics of multiple colors, so their applicability is low.

[0031] Example 2

[0032] Reference Figure 1-6 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the adjustment assembly 4 includes an adjustment box 401 fixedly installed on the outer wall of the mounting frame 5. A rotating rod 402 is rotatably connected to the inner wall of the adjustment box 401. A worm gear 405 is fixedly connected to the outer wall of the rotating rod 402.
